VMM Self-Diagnostics

To activate the diagnostics mode, simultaneously press and hold the "CHECK" and "LIST" switches, then turn the ignition switch to the "RUN" position. With these switches pressed, turn the ignition switch to the "ON" position. The diagnostic program will start and loop continuously. To exit the diagnostic mode, simultaneously press the "CHECK" and "LIST" switches.

There are 2 modes for the diagnostic program: automatic mode and manual mode. In the automatic mode, the program will automatically perform all the tests in sequence. The sequence of tests will repeat until the diagnostic routine is exited. In the manual mode, each test will be performed individually and will only progress to the next test when the "CHECK" switch is pressed. Modes can be changed by pressing the "ENGLISH/METRIC" switch. If the instrument cluster is in the English mode, the program is in the automatic mode. If the instrument cluster is in the Metric mode, the program is in the manual mode.
